It is not clear from the documentation who well OMNA-10 integrates with Homekit (e.g. use on Apple Watch is not mentioned in the literature) and whether I can use Siri Shortcuts (since there doesn't seem to be support for IFTTT). Any insight and suggestions you have are much appreciated!
Cheers

If you set this up for HomeKit using the Home app on your iPhone or iPad running iOS 10 or later then it's available to all your iOS/watchOS devices using the same iCloud account, and anyone else you share access to your Home(Kit enabled home) with.

I am interested in purchasing the D-Link Omna 180 Cam HD. Before I make a decision, I have some questions:

1. I read that data is saved on a SD card. However, is video data also readily transferred to an iCloud account? (To which, I can readily view on my iPhone?) Seems to me that if there is only the availability of local video data storage a SD card in the camera, well, then any burglar with a slight tech background would know to take the SD card or actually the camera with him....

2. With regard to the OMNA app for the iPhone, are snapshots taken, i.e. when motion is detected? Do I receive an immediate warning on my iPhone? Needless to say, the quicker an intruder is detected and pictured, the quicker I can inform the police. Also, having a clear, high quality picture of the intruder would greatly assist in further criminal prosecutions.

I would like to have answers as I seriously want to provide further security to my house (break-ins here are on the increase) and the camera is expensive.

The camera has a stand alone capability and in theory will record to the memory card you install in the bottom. Alternatively you may also use the included D-Link account to store your video / images in the cloud. Either should work from Israel. The cloud storage operation is dependent upon you having an internet connection that is not filtered from D-Link cloud services.

You can set the areas of the video frame where the camera will detect motion, trigger the "motion sensor" in HomeKit and record the video. The video frame is broken into 16 squares each of which can be disabled for motion detection.

On the D-Link website, support section, searching on "DSH-C310", and viewing the FAQs, I found the following answers to two separate questions:

"Apple currently does not support cloud recording via the HomeKit ecosystem for security reasons, so there is currently no way to record video from any HomeKit camera to the cloud. D-Link does not currently offer any alternative cloud recording mechanism, other than a microSD card slot on the camera. You can configure motion detection-based recording which will be automatically saved to a microSD card inserted into the card slot. Recorded video clips can be played back on mobile devices using the Omna app, or the microSD card can be removed from the device and read using a computer."

"The 180 Cam HD’s motion detection feature can trigger alerts when it detects movement within its field of view. This detection can produce a notification on your mobile device, trigger local recording to a microSD card, or initiate an automation policy. Motion detection is turned on by default in both the Omna and Home apps."

If I understand the D-Link answers correctly the answer to your question is NO, it will not record to your iPhone. It will only record to the internal SD Card.
